Is there a European internet phone? - icall internet phone

I travel to Europe and I know that we have an Internet connection from our trip, and I wonder if it reduces an Internet phone service, where I could make calls to or from Europe at a price or free. I searched and found iCall to download.com, but I can well it works and let me in there a good sign program that I can use? Or a website that you can call long distance?
